PACKING DENSITY OF AGGREGATE
The packing density of aggregate gives an indication of how efficiently aggregate fill a certain volume and for that reason is such an important concept in concrete technology.
5 CONSIDERATIONS ON CHOOSING PILE FOUNDATION
FUNCTION OF A PILE FOUNDATION The primary function of a pile foundation is to transfer load to a deeper soil or rock strata. There can be various reason that can force designers to transfer loads to deeper soil or rock strata. For example The soil at shallow depth is weak, i.e., not able to withstand … Read more
10+ TECHNICAL REQUIREMENTS ON DURABILITY OF CONCRETE [IS-456]
From High Strength to High Performance Concrete Durability of concrete is now becoming the major concern for engineers as concrete may deteriorate with time in several ways. The most common durability failures in an outdoor climate are due to reinforcement corrosion or frost attack. In special environments concrete may suffer from chemical attack by various … Read more

WATER PROOFING TREATMENT OF ROOF SLAB [A STEP BY STEP GUIDE]
Water Proofing Treatment of Roof Slab In this method polymer modified cementitious slurry coatings are applied over the base concrete. This technique of waterproofing is latest development in the field of waterproofing. Polymer imparts significant improvement in impermeability. Polymer modified cementitious slurry has coefficient of expansion very similar to concrete thereby it does not get … Read more
4 FUNDAMENTAL FACTORS TO CONSIDER DURING CONCRETE MIX PROPORTIONING
The process of selecting concrete mixture proportions is a process of optimization of several desirable characteristics based on the project requirements. The characteristics to be optimized are economy, strength, durability, and placeability. 1. Economy. The primary reason for systematically determining mixture proportions is economy. The maximum economy can be achieved by minimizing the amount of … Read more
